我正在使用以下内容来创建我的索引文件。
heading_prefix "{\n\\bfseries\\color{black} " % insert in front of letter
heading_suffix "\\hfil}\\nopagebreak\n" % append after letter
headings_flag 1 % turn on headings(uppercase)
delim_0 "\\dotfill"
索引条目出现在一列中，这样就没问题了。我想知道是否有办法让子索引条目出现在多列中，因为它们的长度较短？
以下为一个 MWE 说明：
\documentclass{article}
\usepackage{fontspec,lipsum}
\defaultfontfeatures{Ligatures=TeX}
\setromanfont{Georgia}
\usepackage{index}\makeindex
\makeatletter
\renewenvironment{theindex}
{%\section*{\indexname}%
\setlength\parindent{0pt}%
\setlength\parskip{0pt plus .3pt}%
\let\item\@idxitem
% \vspace*{-25mm}
}
\makeatother

我已使用以下说明来创建索引文件。
xelatex tst.tex
makeindex -s MyIST.ist tst.idx
xelatex tst.tex
evince tst.pdf
MyIST.ist 的内容如下。
heading_prefix "{\n\\bfseries\\ " % insert in front of letter
heading_suffix "\\hfil}\\nopagebreak\n" % append after letter
headings_flag 1 % turn on headings(uppercase)
delim_0 "\\dotfill"
从输出中可以看出，“form”下的所有条目都很短。我想将这些条目排列成 2 列甚至 3 列，而不是像现在这样排列成 1 列。
答案1
计划A设为一段：
\renewcommand\subitem{\unskip\hspace{0pt plus .7\textwidth}\linebreak[3]\hspace{1em plus -.4\textwidth minus .2em}}
\printindex
或者...
计划 B：设置 3 列：
不要重新\subitem定义
heading_prefix "{\n\\bfseries\\ " % insert in front of letter
heading_suffix "\\hfil}\\nopagebreak\n" % append after letter
headings_flag 1 % turn on headings(uppercase)
delim_0 "\\dotfill"
item_x1 "\n\\begin{multicols}{3}\n\\subitem "
group_skip "\n\\ifdim\\columnwidth<\\textwidth\\end{multicols}\\fi\n\n \\indexspace\n"
和
添加
\usepackage{multicol}
答案2
David 计划 A 的变体：使用我的idxlayout包。（注意：使用 MakeIndex 编译以下 MWE没有任何-s選擇。
\documentclass{article}
\usepackage{index}
\makeindex
\usepackage[columns=1,itemlayout=singlepar]{idxlayout}
\usepackage{filecontents}
\begin{filecontents}{\jobname.mst}
heading_prefix "{\n\\bfseries\\ "
heading_suffix "\\hfil}\\nopagebreak\n"
headings_flag 1
delim_0 "\\dotfill"
\end{filecontents}
